l le it known that I, ARGYLE CAMPBELL, a citizen of thewUnited States, residing at Chi-v cago, in the countyof Cook and State of Illinoie, have invented a cer-tain new and useful Improvement in Metallic Car-Roofs, of which the following is a s eeication.

My invention re ates to metallic car roofs. l The object of my invention is'to provide la car roof which can be made Oi? metal to possess a maximum of 'strength for a minimumamount of metal used, Awhich can be easily made and installed and is not readily liable to .get out of order.

It more particularly consists in the use ol exterior carlines above the roof plat-es proper to give strengthening rigidity to the rooi`.

.It also consists in details of. construction which will be hereafter more fully described and claimed. Y

In the drawings, Figure 1 is a plan view partially broken away of a c'arroof embodytral portion or' a earline.

ing my inventionn its preferred form. Fig.

2 is a sectional end view on line 2 oi Fig. L

Fig. 3 is a' sectional end detail view on line 3 of Fig. 1. Fig. 4 is a detail view oi the oen Fig. 5 is a detail view of a portion of the roof lates showing the rid ge-pole and their attac viment thereto. Fig. 6 is anl end detail sectional viewof the upper edge of one side of the car and the means for yattaching the roof plate andear- 'line thereto.

It should be understood that the device oi: my invention is applicable to the sides and ends of any ordinary ear, one form of which is illustrated in Figs 2 and 3 of the drawings, in, Which'thenumeral 10 indicates the sides of a car having on their upper edges longitudinal members 1l, the mem bers being joined by any suitable means to the ends 1'2 el the car.

not shown. In order te give the roof thus eoni vstructed rigidity, I provide upon the Outside of the roof carlines 17 of the corrugated form shown in detail in Fig. 4. On these carlines 17 are fianges 1S ada ted to be secured to the olts or vrivets 'passing vthrough the holes 19 in the carline a'n es and the roof plates at suitable pjoints.I T e outside ends of the carlines are bentdownward over the outside edges of the roof plates 15 in the 'downwardly extending portions 20.

'These-earlines may be Isecured at thel edges of the ear to the upperedges 11 of the sides of the car by suitable bolts or rivets, not shown. In order to give the roof vgreater rigidity I form in the roof plates proper corrugations 22,-

as shown in detail in Figs. l and 3, these serv? ing to stiften the roof in the ordinary manner.

-By this construction I provide a ear roof' without interior obstructions and I-acecmplishthis Without adding to the outside of the car a carline of a'iorm which is at 4all in. the

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is 1. In a metallic car roof the combination with a ridge pole, of continuous metal-roof lates secure-d to said pole and extending i'rom end to end of the ear, said. plates ,having their edges su ported di ectly upon the sides v of the car, an a plurality ol" exterior carlines supported upon and securedito said roofplates.
